From what I understood, the Adaptive has the high beam H7 bulb, and the Bi-Xenon doesn't have the high beam H7 bulb.. But then you say it's the opposite? I guess i'll find out tomorrow when my Bi-Xenons arrive. Will let you know.

You've done the halogen --> Xenon swap haven't you?

Any tips you can add?

They're both bi-xenon lights. The difference being that one version incorporates a halogen high beam as well (non-adaptive) and one version incorporates a "cornering" light instead of the halogen high beam (adaptive). Looking at realoem.com, they unfortunately don't make a distinction between the two types of lights and only show the adaptive lights, which use a H3 bulb for the cornering light AFAIK. Both versions use a H8 bulb for the corona rings, again AFAIK. I'm guessing that the non-adaptive lights use either a H7 bulb for the high beam, or possible a H1 (which seems to commonly be used in small projector assemblies.

No, I haven't done the conversion, but I have done a ton of research about the conversion because I will likely tackle this sometime in the future. I have never actually seen the non-adaptive lights in-person, so most of what I'm saying has been learned through research rather than first-person experiences.

Ok cool well maybe this thread can help you out then for when you decide to take the plunge

It just seemed like there was a general lack of info regarding this here, or people gave up after they did the conversion.

So hopefully this will help once we get some facts! As i said I shall let you know tomorrow

Glad to hear you found the forum. The flicker is due to PWM (pulse width modulation) and can be sorted out with coding. The install process was a PITA but this coding roadblock is the real source of frustration. Hopefully we can figure this out in the near future.

Hmm do you know what needs to be coded to sort the PWM out? What exactly does PWM mean/do?

I have the euro bi-xenon setup in my car currently and can confirm the inner bulb is for the rings only (s/b an H8 based on what I have read here). The high beams are via the shutter only (differs from the e90 setup which has an H7 for the flash function).

The coding portion was the addition of $522 to the VO and disabling the bulb checks. I think the bulb checks might be the issue (car still indicates low/high beam failure on the display). Hope to hear back from Autologic but am not holding my breath at this point (don't think they are familiar with the conversion either). Glad more people are attempting this conversion as most seem to give up.

You need the larger contact for the ground (think you posted the pic of the different ones available earlier in this post).

This doesn't make sense. What are the inner projectors used for? The corona rings are separate and on the outside of the projectors.

There is only one halogen bulb in the main housing (for the corona rings). The design confuses me as well. Once the coding is sorted out the H8 might turn out to be used for flash to pass. Time will tell.

Back in the old days (E30, 36, 46 etc), that inner light was high beam. Now with bi-xenon, one light multi-task. But BMW canít simply delete that because the twin headlights like the twin kidney grills are their DNA.

Hi aacabriolet, I'm still waiting for my headlights to come. All the best to your conversion
